Description

Technical Field

[0001] The invention relates to the technical field of injection molding insert assembly, in particular to a positioning tool based on embedding of injection molding batch inserts and a processing method thereof. Background Art

[0002] In injection molding batch production, embedding of inserts (also called inserts or metal parts) is a common operation. In order to ensure that the inserts are correctly positioned and stable during the injection molding process, and to avoid damage or displacement, special positioning tooling is usually used. The positioning tooling design for embedding inserts involves accurate positioning of inserts, clamping force control, mold matching accuracy, and the application of automated production. Tooling design needs to comprehensively consider many factors based on the specific requirements of the product, the material and shape of the inserts, and the needs of production efficiency. Through precise tooling design, not only can the stability and position accuracy of the inserts be ensured, but also production efficiency can be improved and manual intervention can be reduced.

[0003] The patent with the announcement number CN217169450U discloses a sleeve-type embedding tooling fixture for the manipulator of an injection molding machine, which belongs to the technical field of assembly of injection molding inserts. The fixture is provided with an embedding mechanism on the connecting plate connected to the end of the manipulator, and the embedding mechanism includes a sleeve assembly with a top detachable positioning connection to the connecting plate and a push-up shaft that is positioned and passed through the connecting plate and can be reciprocated and positioned along the axial direction of the sleeve assembly. A clamping part that can clamp and loosen the insert is formed at the end of the sleeve assembly, and the push-up shaft is inserted into the sleeve assembly along the axial direction of the sleeve assembly so that the end of the push-up shaft is inserted into the clamping part and pushes against the insert located in the clamping part. The fixture can avoid the situation that the embedding cannot be performed accurately due to unstable external factors such as mechanical vibration, and can greatly improve the production efficiency, but there is still a problem that multiple inserts cannot be embedded at the same time, which affects the processing efficiency. Therefore, a positioning tooling based on the embedding of injection molding batch inserts and its processing method are proposed to solve the above-mentioned problems. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a positioning tool and a processing method thereof based on embedding of batch inserts by injection molding in view of the deficiencies in the above-mentioned prior art.

The injection molded part is close to the injection molded part, so that the embedded sleeve on the sleeve template is inserted into the outside of the long embedded tube and the short embedded tube connected to the injection molded part. Then, the external transmission mechanism pushes multiple metal inserts to slide along the insert groove on the guide embedding plate. The metal inserts at the corresponding positions in the insert groove fall from the corresponding holes to the bottom of the guide embedding plate and fit into the embedded sleeve, so that the metal insert falls into the long embedded tube or the short embedded tube along the embedded sleeve.

At this time, the energized contact piece connected to the wiring piece contacts the series piece and is energized, so that the current passes through the wiring piece through the energized contact piece and enters the series piece into the heating wire, and then the heating wire passes through the series piece to make the current flow out from the energized piece, so that the heating wire outside the embedded sleeve heats the metal embedded sleeve, allowing the metal insert to contact the long embedded sleeve after being heated. Or the inner wall of the short embedded tube, it can melt the contact part, improve the firmness of the metal embedment, and avoid the short embedded tube or the long embedded tube from cracking due to the metal embedment being squeezed by the extrusion rod. At the same time, part of the heat generated by the heating wire after heating is transferred to the nickel-titanium alloy wire through the contacted temperature control end shell, so that the nickel-titanium alloy wire shrinks after heating and pulls the wiring piece to slide downward along the vertical sliding rod, so that the energized contact piece no longer contacts the extrusion rod after moving downward, and the heating wire is in a power-off state, avoiding the heating wire from continuously heating and melting the energized contact piece and the pressure contact piece.

At this time, the extrusion rod 56 connected to the pressure plate 55 will pass through the corresponding hole position on the guide embedding pressure plate 53, extend to the embedded sleeve 52 to extrude the metal insert into the long embedding tube 58 or the short embedding tube 59, and the lengths of the multiple extrusion rods 56 are correspondingly pressed with different long embedding tubes 58 or short embedding tubes 59, so that the long embedding tubes 58 and short embedding tubes 59 of different lengths on the injection molded part 57 can be embedded with metal inserts at the same time, realizing automatic embedding processing and improving the efficiency of insert processing;

[0036] When the guide and inserting pressure plate 53 approaches the sleeve template 51, the guide and inserting pressure plate 53 drives the connected pressure contact piece 69 to pass through the top of the temperature control end shell 61 to press the top of the wiring piece 67, so that the wiring piece 67 is pressed and squeezes the nickel-titanium alloy wire on the outside along the vertical slide rod 66. At this time, the power-carrying contact piece 68 connected to the wiring piece 67 contacts the series piece 65 and is energized, so that the current passes through the wiring piece 67 and the power-carrying contact piece 68 to enter the series piece 65 and enter the electric heating wire 63, and then the electric heating wire 63 passes through the series piece 64 to make the current flow out from the power-carrying piece 62, so that the electric heating wire 63 outside the embedded sleeve 52 heats the metal embedded sleeve 52, so that the metal insert is heated and contacts the long embedded sleeve 58 or the short embedded sleeve 5 9 inner wall, it can melt the contact part, improve the firmness of the metal insert, and prevent the short insert tube 59 or the long insert tube 58 from cracking due to the extrusion of the metal insert by the extrusion rod 56. At the same time, when the heating wire 63 is heated, part of the heat generated is transferred to the nickel-titanium alloy wire through the contacting temperature control end shell 61, so that the nickel-titanium alloy wire shrinks after being heated and pulls the wiring piece 67 to slide downward along the vertical slide rod 66, so that the energized contact piece 68 is no longer in contact with the extrusion rod 56 after moving downward, and the heating wire 63 is in a power-off state, so as to prevent the heating wire 63 from continuously heating and melting the energized contact piece 68 and the pressure contact piece 69, and realize automatic power off after heating for a period of time, so as to prevent the metal insert from being overheated and affecting the embedding effect and the quality of the insert;

[0037] When the hydraulic lever 4 pushes the pressure plate 55 to move downward, the pressure plate 55 drives the connected pressure folding rod 71 to move downward, so that the pressure folding rod 71 pushes the slide rod 73 to flip around the connection with the hinge seat 72, and pulls the transverse push rod 74 to move horizontally through the flipping of the slide rod 73, and drives the connected transverse push plate 75 and the slide plate 710 to move through the movement of the transverse push rod 74, so that the movement of the slide plate 710 drives the upper injection molded part 57 to move together, and the movement of the transverse push plate 75 causes the linkage rod 77 to slide along the side of the inclined slot plate 76, so that the inclined slot plate 76 moves upward, and pushes the flipping pressure block 712 upward through the inclined slot plate 76 to flip around the connection with the embedded platform 1, so that the flipping pressure block 712 flips and applies pressure on the edge of the injection molded part 57, so as to achieve the positioning and fixation of the injection molded part 57 to avoid embedding. During the process of inserting the metal part, the injection molded part 57 is pressed and deviates from its original position, affecting the embedding effect. In addition, the upward movement of the inclined slot plate 76 drives the piston 78 to contract and discharge the internal air along the connecting pipe 79 to the nozzle 713, so that the discharged air can clean the particles attached to the edge of the injection molded part 57, thereby preventing the residual particles of the injection molded part 57 from affecting the fixing effect of the flip pressure block 712. At the same time, when the slide slot plate 710 moves with the transverse push plate 75, the slide slot plate 710 drives the connected pressing plate 711 to move, so that the flip sheet 714 in the pressing plate 711 contacts the pressure push plate 715 after movement, so that the pressure push plate 715 pushes the flip sheet 714 to flip and buckle the injection molded part 57, thereby preventing the injection molded part 57 from loosening during the process of being embedded in the insert, and promoting the positioning of the injection molded part 57.

At this time, the sleeve template 51 fits the injection molded part 57 and no longer moves to generate an upward reaction force, so that the pressure spring and the return spring begin to shrink, so that the pressure plate 55 approaches the guide insert pressure plate 53, and the guide insert pressure plate 53 approaches the sleeve template 51. At this time, the extrusion rod 56 connected to the pressure plate 55 will pass through the corresponding hole on the guide insert pressure plate 53, extend to the embedded sleeve 52, and extrude the metal insert into the long embedded tube 58 or the short embedded tube 59;

[0042] S4: When the heating wire 63 is heated, part of the heat generated is transferred to the nickel-titanium alloy wire through the contacting temperature control end shell 61, so that the nickel-titanium alloy wire shrinks after being heated and pulls the connecting piece 67 to slide downward along the vertical slide rod 66, so that the energized contact piece 68 moves downward and no longer contacts the extrusion rod 56, and the heating wire 63 is in a power-off state;
